The present invention relates to a three-dimensional molding device for molding a target three-dimensional object.

ある。[Prior Art] Conventionally, as a device for obtaining a resin molded product, there is one that uses an injection molding machine and one that uses a cutting machine to cut the product. , an XY direction movement control device (67), and a Z
The directional movement control device (68) is activated, and at the same time a laser beam (65) is irradiated from the laser light source (66), contour lines are drawn on the photocurable resin WR (61) in the resin liquid tank (63), and the laser beam There is an apparatus in which only the contour line portion hit by the light beam (65) is cured, and then the table (62) is lowered one step and the same operation is performed to mold the cured product (54).
［発明が解決しようとする課題コ

形状の成形は可能である。さらに色換え等の材料変更に
時間がかかる。[Problems to be Solved by the Invention] However, when using an injection molding machine, a mold for the resin mold must be manufactured first, which takes time and cost, especially in the case of the recent wide variety of products. If you try to handle small-volume production, you will need to prepare many molds, which will require more time and cost. In addition, there is a lot of wasted material, such as parts of the runner, and it is possible to mold special shapes such as hollow objects. Furthermore, it takes time to change materials such as changing colors.
切削機によるものは、切削を材料に対し行うため、切り
クズを大量に出し、その結果としてスクラップ材料がた

成形に時間がかかるため、大量生産に向かないといった
ような欠点もある。Since cutting machines cut the material, they produce a large amount of chips, resulting in a large amount of scrap material and high product costs. Another drawback is that it takes time to mold, making it unsuitable for mass production.

可能性も大きい。On the other hand, the apparatus shown in FIG. 6 has a structure in which the photocurable resin is in liquid form in a resin liquid tank, and is cured by irradiating it with a laser beam. Therefore, it can only be molded using a single material. If one were to change the material during the process, the entire photocurable resin in the resin bath would have to be replaced, which would require cleaning and other operations, which would be time consuming and costly. In particular, when changing colors, there is a high possibility that colors will be mixed. Furthermore, it is difficult to control the polymerization of the photocurable resin, and there is a high possibility that the polymerization will proceed to areas that are not irradiated with the laser beam.

Since it is equipped with multiple inkjet nozzles, it is easy to polarize the material during molding and continue shaping.
In addition, since the structure is such that the liquid-curing resin and polymerization initiator are injected from the stage above the inkjet head located below, the possibility that materials changed midway through will mix with the previous material is extremely low. Therefore, highly accurate molding with almost no material sag is possible, and since the two-component curing resin and polymerization initiator are sprayed in the form of small droplets, the polymerization of the resin can be easily controlled.
